user 세션 serialize 문제 질문

Question

[Nest] 25160 - 2021. 09. 28. 오후 10:32:34 ERROR [ExceptionsHandler] Failed to serialize user into session 강의보는 도중에 나왔던 동일한 에러가 나와서 동일한 방법으로, auth.service.ts 파일에 validateUser() 에서 select에 'id'를 추가 하였습니다. 그렇게 했는데도 동일한 에러가 발생해서 user 값을 제대로 받아오는지 확인 하기 위해 console.log를 통해 확인해본 결과 정상적으로 select 한 값들(id, email, password, nickname)을 받아온 것을 확인하였습니다. 그래서 serializer가 제대로 등록되지 않았나 확인하기 위해 github에 있는 sleact를 다운받아 auth 폴더의 < auth.module.ts, auth.service.ts, local-auth.guard.ts, localserializer.ts, local.strategy.ts> app.modules.ts app.service.ts main.ts 등을 확인하고 serialize가 들어 가는 내용을 검색해 보았으나 모두 동일하게 등록되어 있음을 확인하였습니다. 이 상황에서 제가 어느 부분을 중점적으로 살펴 보아야 할지 감이 오지 않아 여쭤보게되었습니다. 에러 문구 : [Nest] 25160 - 2021. 09. 28. 오후 10:32:34 ERROR [ExceptionsHandler] Failed to serialize user into session Error: Failed to serialize user into session at pass (D:\Slack est\dist\main.js:14933:19) at Authenticator.serializeUser (D:\Slack est\dist\main.js:14951:5) at SessionManager.logIn (D:\Slack est\dist\main.js:15239:8) at IncomingMessage.req.login.req.logIn (D:\Slack est ode_modules\passport\lib\http equest.js:50:33) at D:\Slack est\dist\main.js:13559:64 at new Promise () at LocalAuthGuard.

안녕하세요, 제로초님. 답변 주셨는데도 불구하고 늦게 응답해서 죄송합니다. 말씀해주신, https://github.com/ZeroCho/sleact/blob/master/nest-typeorm/src/auth/local.serializer.ts#L18 위치에 있는 console . log ( user ) 자체가 실행이 되지 않습니다. ---------------- auth.service.ts async validateUser 소스코드와 console.log ---------------------- async validateUser ( email : string , password : string ){ const user = await this. usersRepository . findOne ( { where : { email }, select : [ ' id ' , ' email ' , ' password ' , ' nickname ' ] , } ) console . log ( user ) ; if ( ! user ) { return null; } const result = await bcryptjs . compare ( password , user . password ) ; console . log ( result ) ; if ( result ) { const { password , ... userWithoutPassword } = user ; return userWithoutPassword ; } return null; } query: SELECT `Users`.`id` AS `Users_id`, `Users`.`email` AS `Users_email`, `Users`.`nickname` AS `Users_nickname`, `Users`.`password` AS `Users_password` FROM `users` `Users` WHERE ( `Users`.`email` = ? ) AND ( `Users`.`deletedAt` IS NULL ) LIMIT 1 -- PARAMETERS: ["test5@naver.com"] Users { id: 5, email: 'test5@naver.com', nickname: '테스트1', password: '$2a$12$RXFoHQTpSF05vaQ.USsP7e2M15C7Mi/HhY.eHhy.x/gHQx.J6WHTu' } true ---> user.password와 로그인을 위해 입력 받은 비밀번호 비교 값이 동일한지 비교한 결과 값(result) ---------------- local.strategy.ts ----------------- async validate 소스코드와 console.log 부분 async validate ( email : string , password : string , done : CallableFunction ) { const user = await this. authService . validateUser ( email , password ) ; console . log ( ' validate user ' , user ) ; if ( ! user ) { throw new UnauthorizedException () ; } return done ( null, user ) ; } validate user { id: 5, email: 'test5@naver.com', nickname: '테스트1' } ------------- local-auth.guard.ts ------------- 소스코드와 console.log 부분 @ Injectable () export class LocalAuthGuard extends AuthGuard ( ' local ' ) { async canActivate ( context : ExecutionContext ): Promise < boolean >{ const can = await super . canActivate ( context ) ; if ( can ) { const request = context . switchToHttp () . getRequest () ; console . log ( ' login for cookie ' ) ; await super . logIn ( request ) ; } return true ; } } login for cookie 위와 같이 출력됩니다. 위의 내용을 편집 없이 로그만 출력하면 아래와 같습니다. --------------------- 시작 --------------- query: SELECT `Users`.`id` AS `Users_id`, `Users`.`email` AS `Users_email`, `Users`.`nickname` AS `Users_nickname`, `Users`.`password` AS `Users_password` FROM `users` `Users` WHERE ( `Users`.`email` = ? ) AND ( `Users`.`deletedAt` IS NULL ) LIMIT 1 -- PARAMETERS: ["test5@naver.com"] Users { id: 5, email: 'test5@naver.com', nickname: '테스트1', password: '$2a$12$RXFoHQTpSF05vaQ.USsP7e2M15C7Mi/HhY.eHhy.x/gHQx.J6WHTu' } true validate user { id: 5, email: 'test5@naver.com', nickname: '테스트1' } login for cookie [Nest] 29836 - 2021. 09. 29. 오후 9:06:02 ERROR [ExceptionsHandler] Failed to serialize user into session Error: Failed to serialize user into session at pass (D:\Slack est\dist\main.js:14934:19) at Authenticator.serializeUser (D:\Slack est\dist\main.js:14952:5) at SessionManager.logIn (D:\Slack est\dist\main.js:15240:8) at IncomingMessage.req.login.req.logIn (D:\Slack est ode_modules\passport\lib\http equest.js:50:33) at D:\Slack est\dist\main.js:13559:64 at new Promise () at LocalAuthGuard.

https://github.com/ZeroCho/sleact/blob/master/nest-typeorm/src/auth/local.serializer.ts#L18 여기에 console.log 찍은 건 어떻게 뜨시나요?
